Step-by-step explanation:
When you're drawing an inequality on a number line there are a few things to focus on:
- Whether your variable is greater than or less than the number
- Whether it can be equal to the number or not
If it can be equal to the number your first dot will be filled in, if not it will be hollow
When it's less than it means you're moving to the left on your number line, if it's greater than you move right

An employee of a company wants to determine what method of transportation most employees use to get to work. Which sample is the most representative of the population of interest? 20 randomly selected employees in the marketing department 20 randomly selected employees in the marketing department 50 randomly selected employees at the company 50 randomly selected employees at the company all the first-year employees at the company all the first-year employees at the company the first 25 employees to get to work Monday morning the first 25 employees to get to work Monday morning
Using sampling concepts, it is found that the most representative sample of the population of interest is given by:
50 randomly selected employees at the company.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which has to involve all groups in the population.
In this problem, all employees have to be considered, no matter their department or experience on the company, hence the most representative sample of the population of interest is given by:
50 randomly selected employees at the company.

Find the GCF of each pair of terms.
3 and 9
Answer:
The GCF is 3.
Step-by-step explanation:
All you do is list out the factors of the numbers and find the greatest factor that they have in common.
Like the GCF of 3 and 9. We list the factors.
Factors of 3:
1, 3
Factors of 9:
1, 3, 9
As we can see, 3 is the GCF because it is the highest factor that the numbers have in common.

if △ ABC ~ △A'B'C' and AC=20cm,A'C'=15cm,B'C'=12cm andA'B'=9cm find the lengths of the other sides of △ABC.
Answer:
AB=12 BC=9
Step-by-step explanation:
Any side of a triangle must be shorter than the other two sides added together.
AB and A'B' must measure LESS than the other 2 sides
15 is 3/4 of 20
12 is 3/4 0f 9

Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,000 feet wide .If astin's replica has a width of 60 centimeters, what is the height of his empire state building replica rounded to the nearest centimeter?
Answer: 14cm
Step-by-step explanation:
From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide
We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet
= 60:6000
= 1:100
Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:
= 1423/100
= 14.23cm
= 14cm approximately
Determine whether one figure is a dilation of the other. Complete the justification.
Quadrilateral DEFG has side lengths of 16 m, 32 m, 28 m, and 12 m. Quadrilateral D'E'F'G' has side lengths of 44 m, 88 m, 77 m, and 33 m.
The figure D' E' F' G' (is/is not) a dilation of the figure D E F G. Thr ratios of the lengths of the corresponding sides (are not/are) equal.
Answer:
is a dilation
Step-by-step explanation:
One of the triangles will be a dilation of the other if corresponding sides have the same ratio. When given a series of side lengths, there are a couple of ways you can determine if the ratios are the same.
compute the ratio of the side of one figure to the corresponding side of the other figureput corresponding side lengths in order around the figure, and remove any common factor from their values.Sometimes the latter approach is easier.
__
DEFG ratios are 16 : 32 : 28 : 12 = 4 : 8 : 7 : 3 . . . . . . remove a factor of 4
D'E'F'G' ratios are 44 : 88 : 77 : 33 = 4 : 8 : 7 : 3 . . . . remove a factor of 11
The figure D'E'F'G' is a dilation of the figure DEFG. The ratios of the lengths of the corresponding sides are equal.
Suppose a triangle has two sides of length 3 and 4 and that the angle
between these two sides is 60°. What is the length of the third side of the

A student attempted to generate an equivalent expression using the distributive property, as shown below:
3(p − 4) = 3p − 4
What was the mistake made? (1 point)
a
3 was not multiplied by p
b
3 was not multiplied by −4
c
Incorrect sign was used for the first term
d
Incorrect sign was used for the second term
20 POINTS HELP ASAP
Answer:
b 3 was not multiplied by −4
Step-by-step explanation:
The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.
3(p − 4) = 3p + 3 × (-4) = 3p - 12
His attempt is
3(p - 4) = 3p - 4
He did multiply 3 by p, but h did not multiply 3 by -4.
Answer: b 3 was not multiplied by −4

Answer:
a) 5 units
Step-by-step explanation:
Pythagorean Theorem : c^2 = b^2 + a^2
so
VW^2 = 3^2 + 4^2
VW^2 = 9 + 16 = 25
VW = 5
